NEW QUESTION # 62
Which HTML tag should a developer use to create a drop-down list?

A. <Output>
B. <Select>
C. <Option>
D. <Section >

Answer: B

Explanation:
The <select> tag is used in HTML to create a drop-down list. It is used in conjunction with the <option> tags to define the list items within the drop-down menu.
* Purpose of <select>: The <select> element is used to create a control that provides a menu of options.
The user can select one or more options from the list.
* Structure of Drop-down List:
* The <select> element encloses the <option> elements.
* Each <option> element represents an individual item in the drop-down list.
* Usage Example:
<label for="cars">Choose a car:</label>
<select id="cars" name="cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat">Fiat</option>
<option value="audi">Audi</option>
</select>
In this example, the <select> tag creates a drop-down list with four options: Volvo, Saab, Fiat, and Audi.
* Attributes of <select>:
* name: Specifies the name of the control, which is submitted with the form data.
* id: Used to associate the <select> element with a label using the <label> tag's for attribute.

NEW QUESTION # 64
Given the following CSS statement:

Which code segment changes the font color when the viewport is 800 pixels wide or wider?

Answer: A

Explanation:
To change the font color when the viewport is 800 pixels wide or wider, a media query with min-width:
800px is used. This ensures that the styles inside the media query are applied only when the viewport width is at least 800 pixels.
* CSS Media Queries:
* Syntax for Media Query:
@media screen and (min-width: 800px) {
body {
color: black;
}
}
* Explanation: The min-width: 800px condition ensures that the styles are applied when the viewport is 800 pixels or wider.
* Example Analysis:
* Option A:
@media screen and (min-width: 800px) {
body {
color: black;
}
}
* Correct. This applies the color: black; style to the body when the viewport is 800 pixels or wider.
* Option B:
@media min-width: 800px {
body {
color: black;
}
}
* Incorrect. Missing screen and which is required for a proper media query targeting screens.
* Option C:
@media screen and (max-width: 800px) {
body {
color: black;
}
}
* Incorrect. This applies the style when the viewport is 800 pixels or narrower.
* Option D:
@media max-width: 800px {
body {
color: black;
}
}
* Incorrect. This applies the style when the viewport is 800 pixels or narrower.
* References:
* MDN Web Docs - Using media queries
* W3Schools - CSS Media Queries
The correct use of media queries ensures that the specified styles are applied only under the desired conditions, providing a responsive design.

NEW QUESTION # 65
Given the following CSS code:

Which type of selector is used?

A. ID
B. Element
C. Group
D. Class

Answer: A

Explanation:
The given CSS code uses the #name selector, which is an ID selector. The ID selector is used to style an element with a specific id attribute.
* ID Selector: In CSS, the ID selector is used to style the element with the specific id. The syntax for the ID selector is #id, where id is the id attribute value of the HTML element.
* Usage Example:
#name {
text-align: left;
}
This CSS rule will apply the text-align: left; style to the element with id="name".
* ID Selector Characteristics:
* An ID must be unique within a document, meaning it can be used only once per page.
* ID selectors are more specific than class selectors and element selectors.
* Example in HTML:
<div id="name">This is a div with ID "name".</div>

* MDN Web Docs on CSS Selectors
* W3C CSS Specification on Selectors

NEW QUESTION # 66
What is the purpose of cascading style sheets (CSSs)?

A. Providing functionality that was previously provided by plug-ins
B. Structuring and describing web page content
C. Setting rules to define how page content looks when rendered
D. Changing the content of a web page dynamically

Answer: C

Explanation:
Cascading Style Sheets (CSS) are used to control the presentation of web pages, including aspects such as layout, colors, fonts, and other visual styles. They are a cornerstone technology of the World Wide Web, along with HTML and JavaScript. Here's a detailed breakdown:
* Purpose of CSS: CSS is designed to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting, and reduce complexity and repetition in the structural content.
* Setting Visual Rules: CSS allows developers to define rules that specify how different elements of a web page should be displayed. For example, CSS rules can change text color, font size, spacing between elements, and even the overall layout of the web page. These rules are applied by the browser to render the web page according to the defined styles.
* Cascading Nature: The term "cascading" in CSS refers to the process of combining multiple style sheets and resolving conflicts between different CSS rules. This allows developers to use different sources of style information, which can be combined in a hierarchical manner. For instance, a browser style sheet, an external style sheet, and inline styles can all contribute to the final rendering of a web page.
* Benefits of CSS:
* Consistency: By using CSS, developers can ensure a consistent look and feel across multiple web pages.
* Maintainability: CSS makes it easier to update the visual presentation of a web page without altering the HTML structure. This is particularly useful for maintaining large websites.
* Reusability: CSS rules can be reused across multiple pages, reducing redundancy and making it easier to implement changes globally.
* Examples of CSS:
css
Copy code
body {
background-color: lightblue;
}
h1 {
color: navy;
margin-left: 20px;
}
In this example, the body element is given a light blue background color, and the h1 element is styled with a navy color and a left margin of 20 pixels.
